I received a 6390 RDS in 3 weeks with Cordura multicam even after ordering during there 40% September sale event. WRS is complete junk. Just wait for the right gear, as it is not something to cheap out on or get something that’s “good enough”.
Squared Away Customs in Enfield nh makes Kydex duty holsters that use the Safariland SLS hood and belt loop. The make holsters for Rome equiped guns.Ymmv
Have used modified 6280s for patrol and teaching. They will suffice, but they're not ideal.
Have one of the new purpose-built Safariland holsters; however, it is weirdly snug, and I can't find the friction point(s).
Hadn't heard about Squared Away Customs as a possible duty alternative. There is also Long's Shadow Holsters. I am planning on trying a Spetz Gear holster to see, one way or another.
